[0034] The utility model is further described below in conjunction with the accompanying drawings.
[0035] A handheld vacuum cleaner, such as Figure 1-2 and Figure 7 As shown, it includes a handle portion 1, a straight tube portion 2 and a floor brush portion 3. The handle portion 1 is detachably equipped with a dust cup 4. The handle portion 1 and the floor brush portion 3 are provided with a dust suction channel 3c connected to the tube cavity of the straight tube portion 2. A roller 31 is provided on each side of the bottom of the floor brush portion 3. A plurality of magnets 311 are provided in the roller 31 at intervals along the circumferential direction. The floor brush portion 3 is provided with an electrically connected Hall sensor 32 and a control board 33. A UV sterilization light strip 34 electrically connected to the control board 33 is provided on the front end side wall of the floor brush portion 3, and the UV sterilization light strip 34 is tilted downwardly arranged on the floor brush portion 3. When the roller 31 rolls, the Hall sensor 32 and the magnet 311 in the roller 31 are induced and cooperated, and the UV sterilization light strip 34 is controlled to turn on through the control board 33; an anti-collision strip 37 is provided on the side wall of the floor brush portion 3 corresponding to the UV sterilization light strip 34, and the anti-collision strip 37 is arranged in parallel below the UV sterilization light strip 34.
[0036] like Figure 2-6As shown, the Hall sensor 32 is integrated on the control board 33, the floor brush portion 3 is provided with a receiving cavity 3a and a light bar mounting hole 3b, the control board 33 and the Hall sensor 32 are built in the receiving cavity 3a, and the UV sterilizing light bar 34 is installed in the light bar mounting hole 3b. Integrating the Hall sensor 32 on the control board 33 is conducive to saving the installation space of the Hall sensor 32, and the UV sterilizing light bar 34 can realize oblique irradiation of the ground through the light bar mounting hole 3b; the floor brush portion 3 is provided with a heat dissipation structure corresponding to the control board 33, and the heat dissipation structure is used to dissipate the heat generated by the control board 33. The heat dissipation structure can effectively realize the release of the heat generated by the control board 33, and prevent the relatively closed receiving cavity 3a from being heated. The control board 33 output line is damaged due to overheating; the heat dissipation structure includes an air suction channel 3d which runs through the side wall of the front end of the floor brush portion 3, the air suction channel 3d is connected to the dust suction channel 3c, and the side wall of the air suction channel 3d is close to the inner wall of the accommodating chamber 3a. When the vacuum cleaner is running, a vacuum suction force is generated in the dust suction channel 3c, so that the air suction channel 3d connected to the dust suction channel 3c also generates suction, and the cold air in the external environment is sucked into the air suction channel 3d. The heat generated by the control board 33 will be transferred to the inner wall of the accommodating chamber 3a, and finally heat exchange with the cold air is achieved, thereby effectively reducing the temperature in the accommodating chamber 3a; in this embodiment, the air suction channel 3d is opened between the UV sterilization light strip 34 and the anti-collision strip 37.
[0037] like Figure 6 As shown, an aluminum partition 35 is provided between the air suction channel 3d and the accommodating chamber 3a. The aluminum partition 35 is used to isolate the accommodating chamber 3a from the air suction channel 3d. The aluminum partition 35 has high thermal conductivity. The aluminum partition 35 can be used to quickly conduct the heat in the accommodating chamber 3a to the cold air flowing through the air suction channel 3d, thereby realizing rapid heat dissipation of the control board 33; a plurality of heat dissipation holes 35a are provided on the aluminum partition 35 at intervals, and the heat in the accommodating chamber 3a can be partially discharged through the heat dissipation holes 35a on the aluminum partition 35, thereby realizing The heat in the accommodating chamber 3a can be quickly discharged, so as to achieve the purpose of rapid cooling; a one-way breathing membrane 351 is provided in the heat dissipation hole 35a, and the one-way breathing membrane 351 allows the heat in the accommodating chamber 3a to enter the suction channel 3d in one direction. The one-way breathing membrane 351 can allow the heat in the accommodating chamber 3a to flow into the suction channel 3d in one direction, and can also prevent the water vapor or dust in the suction channel 3d from entering. While ensuring the rapid and large-scale discharge of heat from the accommodating chamber 3a, it can also effectively improve the dustproof and waterproof performance of the control panel 33 of the utility model.

[0039] The basic working principle of the utility model is as follows: after the vacuum cleaner is turned on, dust passes through the dust suction channel 3c of the floor brush part 3 along with the air flow, passes through the straight tube part 2 and the handle part 1 in turn, and then enters the dust cup 4. When the vacuum cleaner is cleaning, the roller 31 rolls on the cleaning surface. During the rolling of the roller 31, the magnet 311 inside it rotates. The Hall sensor 32 senses and detects the magnetic field change around the magnet 311 and feeds back the magnetic field change signal to the control board 33. The control board 33 controls the UV sterilization light strip 34 located on the front side wall of the floor brush part 3 to turn on and irradiate the cleaning surface for sterilization. When the pushing of the floor brush part 3 stops, the roller 31 stops rotating synchronously. At this time, the Hall sensor 32 senses the signal that the magnet 311 stops rotating and feeds back the signal to the control board 33. The control board 33 controls the UV sterilization light bar 34 to cut off the power, so as to realize the automatic start and stop of the UV sterilization light bar 34. While saving electricity, it can also prevent the UV sterilization light bar 34 from irradiating the eyes and causing damage to the eye membrane when the vacuum cleaner is picked up. The UV sterilization light bar automatically opens and closes, saves energy, and prevents the UV sterilization light bar from accidentally irradiating the eyes and causing damage to the eye membrane when the vacuum cleaner is picked up.
